The second-order linear homogeneous differential equations in differential equation theory occupies an important position, but the second order differential equation has no general solution method, most of the solutions of these equations is difficult to obtain analytical expressions and even some impossible to obtain the solution of the form, and the second order differential equation solving is divided into homogeneous and inhomogeneous problems.

二阶线性齐次微分方程在微分方程理论中占有重要位置，但二阶变系数微分方程却没有一般的求解方法，大多数这类方程很难求得解的分析表达式甚至有的根本不可能求得其解的分析形式，并且二阶变系数微分方程的求解又分为齐次的和非齐次的问题。

It implies that the calculation of movements of mobile cells is not accurate enough, that must affects the mass exchange between the mobile cells and immobile cells. Furthermore, because the value of concentration be calculated is always at center of an element and the finite difference grid is fixed, which may gives rise to numerical dispersion, especially when the steps of space are injudiciously selected.

另一方面，颗粒的位置直接影响到其所含各种成分的质量变化，这将在一定程度上影响最终各种成分的浓度计算精度，而且，该算法最终统计各种成分的浓度时，所用的窗口也是已有的固定的有限差分网格，当网格选择不合适时，有可能产生人工数值弥散。

"We looked at all sorts of biological markers that could potentially play a role in linking depression and heart disease," says Dr. Mary Whooley, an internist at the VA Medical Center in San Francisco, and lead author of the new study. We measured all of those, and found that they did not explain the association.
